hi all i've had a post running for a while now with no response so thought i'd try the message board , im after a cdi unit for my mc21 ( pgm III) or someone who could repair mine , it has a damaged capactor on the ignition side but the black gunk they fill these things with is preventing me form trying to do this myself, there must be a spare one out there some were, any help at all i would be most greatfull. cheers all.
